AUTOMATIC GAS-LIGHTING APPARATUS.

SPECIFICATION forming part of Letters Patent N o. 626,247, dated June 6, 1899.

Application led April l2, 1898.

To @ZZ whom t may concern.-

Be it known that we, STANISLAW RosINsKI, civil engineer, of 95 Avenue de Versailles, and MARIE MARGUERITE DUCRUIX, widow of Ernest Ducruix, of 104cm Boulevard Exelmans, Paris, France, have invented Improvements in Automatic Gas-Lighting Apparatus, of Which the following is a full, clear, and exact description.

Our invention, which is applicable to gasburners generally, relates to the automatic lighting of gas by the mere act of turning on the gas to the burner.

The invention consists,essentially,in means for effecting the automatic closure of the branch passage by the expansion of a iiuid or any other expansible body acting upon an elastic bulb or partition in such manner as to cause the latter on the expansion of the fluid under the action of the heat of the burner to shut oi the branch passage. This device consists, essentially, of a tube or receptacle having one end closed and the other open, but inclosed by an elastic cap or bulb ot' india-rubber, the said tube containing mercury and a certain volume of air which under the action of the heat of the lighted burner is caused to dilate and so expand the elastic cap or bulb which` is applied t0 act as a valve to effect the closure of the passage of the gas through the branch passage. On the gas being turned off the air and mercury cool and contract, the elastic membrane resumes its original form, and the passage is opened in readiness for the turning on of the tap of the burner.

Our invention is illustrated in the accompanying drawings as applied to various known types of gas-burners- Figures l to 5 show a device embodying our invention applied to abats-Wing burner, Fig. l being an elevation of the device, Fig. 2 a side View thereof, Fig. 3 a vertical section thereof, Fig. 4 a plan view thereof, and Fig. 5 a horizontalsection on line l 2, Fig. l. Figs. G, 7, and 8 show front, side, and sectional views, respectively, ot' the device applied to an ordinary gas-burner. Fig. 9 shows the application of the device to an incandescent gas-burner. Fig. l0 shows an elevation, and

Serial No. 677,289. "No model-7 Fig. 1l an underneath View, of the device ap-v plied to a Bengel burner.

The same letters of reference indicate the same parts in all the iigures.

In the gures, a is a 'metal block having a passage b, Whose upper end forms a valve-seat and communicates with the gas-supply passage leadingto the burner and with a chamber c of slightly largerdiameter, from Which leads a passage cl, terminating in an upwardly-di rected nozzle d', by which the jet of gas admitted through b is directed onto the pellet of material e, capable of being rendered incandescent by the gas and preferably composed of gelatinous alumina steeped in a solution of platinum chlorid containing one gram of platinum chlorid to four grams of alcohol. The pellet c, which should be in proximity to the burner, is mounted on a support f, screwed to the block a, and in order to obtain a more extended incandescent surface a cluster of platinum Wires e extend down from the pellet e to the base of support f.

The device by which the gas is shut off from the nozzle d when the gas is lighted consists of a suitable passage-closing device, here shown as comprising an upright straight rigid tube or receptacle g, screwed into the chamber c. This tube is closed at its upper end, and its open lower end is closed by a bulb 0r partition h, of elastic material, such as indiarubber, and the tube is lled with mercury and a certain volume of air. When the gas is lighted at the burner, the tube g becomes heated, the contained air and mercury become dilated, and the bulb h is expanded and closes thepassage l).

To adapt the improved automatic lighter to a bats-Wing burner, the tip t' is connected to the gas-inletj by two or three tubes 7c, the channel l) in this case branching directly from the gas-inlet 7', as shown in Fig. 3, and the upper end of the mercury-tubefg is rounded,

so as to conform to the shape of said tip,

through Which it extends. The Whole is inclosed in a casing l, open at its upper end, which casing serves to direct the gas from the tube d' to the automatic igniting device e f. Bats-Win g burners may thus be provided ICC) with an automatic lighting device withoutl altering their general form and be screwed onto existing gas-fittings, like ordinary burners.

The device shown in Figs. Gto 8 is adapted when made ot' proper size for use on burners ot' all suitable kinds and dimensions. To enable the position of the pellet of incandescible material e to be adjusted relatively to the burner, the block a is mounted upon a tube m,conuected with channel b, and fitted to slide in another tube n, branched upon a unionpiece o, screwing onto the gassnpply pipe below the burner, as shown in Fig. 9, which illustrates the application ot the device to an incandescent gas-burner. The tube m is clamped at any suitable height in tube fn, by any ordinary means. The device is inclosed in a protective and gas-directing casing Z, as before.

Figs. 10 and ll'show the automatic lighting device as mounted upon a Bengel burner. In this ease the tube m screws into gas-inletj.

Our improved automatic lighting device presents the great advantageof com pactness and of being` readily adaptable to existing apparatus. It is also of very simple construction and not liable to getout of order, thus insuring an efficient action.

We do not herein claim the incandesciblc body nor its application, as described herein, as the same forms the subject matter of another application tiled by us this day, Serial No. 677,290.

XVe claiml. In a device for automatically igniting gas by means ofan auxiliary gas-supply acting on an incandescible material, the combination of a main burner, a material capable of being rendered incandescent by the contact of gas therewith and in igniting proximity to the main burner, an auxiliary gas-sup- 4o ply passage for directing a low of gas upon said material and athermostatic passage-closing device comprising in its structure a straight rigid tube closed at its lower end by an elastic membrane and containing mercury and a volume of air, the said membrane being in operative proximity to the auxiliary gassupply passage whereby upon dilation of the air and mercury the elastic membrane will be stretched and will contact withthe auxiliary 5o suppl y-passage thereby closing the same.

2. In a device of the character described, the combination of a gas-supply, a tube containing mercury and air and provided at its lowerend with an expansible partition in op- 55 erative proximity to the gas-supply whereby fupon dilation of the mercury the elastic partition will contact with the gas-supplypassage and thereby close the same and a casing e surrounding Ithe gas-supply, mercury-tube 6o and incandescible material for directing the gas upon the incandescible material.

The foregoing speciiication of our improvements in automatic gas-lighting apparatus signed by us this 31st day of March, 1898.
